Preheat the Oven
Preheat your oven to 400°F (200°C).
Generously grease a standard 12-cup muffin pan with butter or nonstick cooking spray.
Pay special attention to the sides of each cup because the cheese can stick as it melts.
Step 2: Mix the Potato Batter
Place the cold mashed potatoes in a large mixing bowl.
Add:
- Eggs
- Cheddar cheese
- Parmesan cheese
- Green onions or chives
- Garlic powder
- Black pepper
Mix until everything is evenly combined.
Taste a small amount and add salt only if needed. Mashed potatoes and cheese can already contain plenty of salt.
Step 3: Fill the Muffin Pan
Divide the potato mixture evenly among the prepared muffin cups.
Each cup should be nearly full.
Press the mixture down gently with the back of a spoon, then lightly round the tops.
Sprinkle a little extra cheddar or Parmesan over each puff if desired.
Step 4: Bake Until Golden
Bake for 20 to 25 minutes, or until:
- The tops are golden
- The edges are crisp
- The cheese is melted
- The centers are heated through
For deeper browning, bake for an additional 2 to 4 minutes while watching closely.
Step 5: Let Them Rest
Remove the pan from the oven and allow the potato puffs to rest for 5 to 10 minutes.
This step is important.
The puffs are delicate when they first come out of the oven. Resting helps them firm up so they can be removed without breaking.
Run a thin butter knife around the edge of each puff, then gently lift it from the pan.
How to Get Extra-Crispy Potato Puffs
For crispier edges:
- Grease the muffin pan generously
- Use cold, thick mashed potatoes
- Avoid adding too much milk or cream
- Fill the cups almost to the top
- Bake until the edges are deeply golden
- Let the puffs rest before removing them
A metal muffin pan usually creates crisper edges than a silicone pan.

Can I Make Them Ahead?
Yes.
Prepare the potato mixture and fill the greased muffin pan.
Cover and refrigerate for up to 24 hours.
When ready to bake, remove the pan from the refrigerator while the oven preheats.
You may need to add 3 to 5 minutes to the baking time because the mixture will be very cold.
How to Store Leftovers
Allow the puffs to cool completely.
Store them in an airtight container in the refrigerator for up to 4 days.
Place parchment paper between layers to prevent them from sticking together.
How to Reheat Potato Puffs
For the best texture, reheat them in the oven or air fryer.
Oven
Bake at 350°F (175°C) for 8 to 10 minutes.
Air Fryer
Air fry at 350°F (175°C) for 4 to 6 minutes.
Microwave
Microwave in short intervals until warm.
The microwave works, but the edges will be softer.
Can You Freeze Cheesy Mashed Potato Puffs?
Yes.
Allow the baked puffs to cool completely.
Arrange them in a single layer on a tray and freeze until firm.
Transfer them to a freezer-safe container or bag and freeze for up to 2 months.

Frequently Asked Questions
Why Did My Potato Puffs Fall Apart?
The mixture may have been too wet, or the puffs may not have rested long enough after baking.
Add a small amount of flour or breadcrumbs if the batter seems loose, and let the puffs cool in the pan before removing them.
Can I Use Instant Mashed Potatoes?
Yes.
Prepare them according to the package directions, but use slightly less liquid so the potatoes remain thick.
Chill completely before making the puffs.
Can I Make Them Without Eggs?
Eggs provide structure, so removing them will change the texture.
You can experiment with a commercial egg substitute, but the puffs may be softer and more fragile.
What Cheese Works Best?
Cheddar is a classic choice, but you can also use:
- Monterey Jack
- Gruyère
- Gouda
- Mozzarella
- Pepper Jack
- Colby Jack
A mixture of cheeses often gives the best flavor.
Can I Use Sweet Potatoes?
Yes.
Use thick mashed sweet potatoes and reduce any added sugar. Cheddar, Parmesan, sage, and black pepper pair especially well with sweet potatoes.
